Re: Integrating OSDs from a previous Ceph installation

I've already tried that. No use. Cephadm has a problem with the hostname: mixtile@blade3n1:~$ sudo ceph cephadm osd activate blade3n1 Error EIO: Module 'cephadm' has experienced an error and cannot handle commands: invalid literal for int() with base 10: 'blade3n1' I know that one or two people have had this error so far, but I have not found a remedy. Neither did cephadm deploy work: mixtile@blade3n1:~$ sudo cephadm deploy --osd-fsid 9f7fd40d-0698-40b9-8718-62942 b03e263 --name osd.blade3n1 --fsid 8aad3073-39a1-11f1-bf6e-f2704a1efa9b --keyrin g /var/lib/ceph/8aad3073-39a1-11f1-bf6e-f2704a1efa9b/osd.blade3n1/keyring Deprecated command used: <function command_deploy at 0xffffa333cea0> Non-zero exit code 1 from /usr/bin/docker container inspect --format {{.State.St atus}} ceph-8aad3073-39a1-11f1-bf6e-f2704a1efa9b-osd-blade3n1 /usr/bin/docker: stdout /usr/bin/docker: stderr Error response from daemon: No such container: ceph-8aad 3073-39a1-11f1-bf6e-f2704a1efa9b-osd-blade3n1 Non-zero exit code 1 from /usr/bin/docker container inspect --format {{.State.St atus}} ceph-8aad3073-39a1-11f1-bf6e-f2704a1efa9b-osd.blade3n1 /usr/bin/docker: stdout /usr/bin/docker: stderr Error response from daemon: No such container: ceph-8aad 3073-39a1-11f1-bf6e-f2704a1efa9b-osd.blade3n1 Deploy daemon osd.blade3n1 ... Shouldn't it create the necessary container itself? BTW, I've found out that the utilities ceph-osd, ceph-base, and ceph-volume were installed for some reason. I removed them, but that didn't help me either.

I haven't used ifconfig for a while now (using netplan), but us much as I remember, `mtu 9000` setting for br0 should suffice. I.e. no eth0 stanza and no pre/post ip link actions. As for OVN interference — why not temporarily disable it as a test? -- Šarūnas Burdulis Dartmouth Mathematics math.dartmouth.edu/~sarunas · https://useplaintext.email ·

CSC minutes 2026/06/08

Minutes from today's meeting of the Ceph Steering Committee: - *https://github.com/ceph/ceph/pull/68892 <https://github.com/ceph/ceph/pull/68892> PR to effect https://tracker.ceph.com/issues/76442 <https://tracker.ceph.com/issues/76442>* - The proposal is to continue the discussion on the PR - *Permissions to add/update "Labels" in redmine? Requires user to be admin/owner. Should PTLs be a part of those roles?* - The issue is custom fields concept in Redmine that can only be changed/added by a Redmine superuser (or admin) - Not a usual event (few times a year across components), just ask existing admins to create the labels for you - New Business - Debate on: - Motion: https://tracker.ceph.com/issues/76666 - Motion: https://tracker.ceph.com/issues/76648 - https://tracker.ceph.com/issues/76755 - https://tracker.ceph.com/issues/76682 - Election to vote on CSC member removals based on past (few) election participation - draft in https://tracker.ceph.com/issues/76665 - Election votes are not public (implementation of the process can be challenging) - Several concerns about whether that would be possible or not - *Can we fork OpenKMIP/PyKMIP: A Python implementation of the KMIP specification into Ceph GitHub? We need it for example in nvmeof gw, and it is currently unmaintained so we suggest to do it under ceph * - There's no community formed for those unmaintained projects. - Practical risks: security, no new Python versions support, etc - Used by SMB containers, nvmeof and probably by rgw - No clear forks with strong community - There was no immediate conclusion; concerns remain about what the fork implies - Simply having a fork doesn't imply a particular maintenance level - Need to revisit topic again later - *groups.io <http://groups.io> migration (?)* - Your Name on behalf of This List is a requirement - Not clear if this is a real requirement for mailing lists - No way disable receiving multiple copies sent to multiple lists - the alternative seems to be moving back the service to self-managed solution - Lab network policies can prevent from running a mail server on their infrastructure. * New Ceph Security Working Group approval * - Action item: Create a motion in Redmine

MTU Change not going as planned
by filip Mutterer 08 Jun '26

Hi! I am trying to set the MTU to 9000. ip link set dev br0 mtu 9000 It does work after running the command. ip link show br0 4: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc noqueue state UP mode DEFAULT group default qlen 1000 link/ether 22:6c:63:46:7e:67 brd ff:ff:ff:ff:ff:ff But adding it to my configuration like this: auto lo iface lo inet loopback auto eth0 iface eth0 inet manual pre-up ip link set dev eth0 mtu 9000 auto br0 iface br0 inet static address 192.168.1.41 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 192.168.0.113 bridge_ports eth0 bridge_stp off bridge_fd 0 mtu 9000 post-up ip link set dev br0 mtu 9000 The result after a restart is eth0 got MTU 9000 but br0 sticks to 1500. I can change it and seems to work fine. Tested it like that: ping -M do -s 8950 192.168.1.42 Also I noticed runing service networking restart && ip link show br0 Shows the MTu 9000 is set once. I also have an working OVN and OpenVSwitch on that machines. Is it OVN/OVS that makes it comming out like that? Greetings filip

Hi Yuri, There are still failures like: https://qa-proxy.ceph.com/teuthology/pdonnell-2026-06-01_16:46:10-orch-tent… : could be fixed with [1] but it is not going to be included in 20.2.2 as the milestone was replaced by 20.2.3, see [2] https://qa-proxy.ceph.com/teuthology/pdonnell-2026-06-01_16:46:10-orch-tent… : seems to be a valid issue in orchestrator (cephadm doesn’t actually stop OSD deamons before making ceph-volume zap the underlying device) From ceph-volume perspective, the other failures I see are unrelated or due to infra/job definition issues.
